This invention relates to improvements in change making'devices providedwith means for carrying coins and means operable to discharge coins fromthe carrying means.

An object ofthe invention is to provide a change maker of novel,inexpensive and efiic'ient construction wherein the coins may be causedto fall from the device more nearly in a vertical direction, and whereinthe coins may be inverted and stacked one upon another in the hand ofthe user of the device as the coins are discharged from the device. y

Another object of the invention is to 1 eliminate the use of screws,bolts, nuts and rivets in securing the parts of the device together.

Another'object of the invention is to improve the severalelements of theframe 29 structure and coin ejecting mechanism of the device wherebyadvantages not heretofore present are gained.

The invention resides'in the elements and the combinations of themhereinafter de- 1 5 scribed and claimed. I I

Figure le is a side view of one of the 56 coin tubes.

Referring to the drawings, the frame structure of. the device comprisesa bent sheet metal member 2 and a series of vertically-disposed, spacedtubes}; of varying no sizes adapted to receive and carry coins ofvarying diameters. Thesheet metal member 2,.as herein illustrated, isformed of a singlepiece of material and it comprises a top plate 7, abottom plate 8 and a rear plate 9 connecting the top and bottom plates.The forward portion of the top plate 7 is provided with semi-circularcutout portions to conform to the several tubes 3 andto form bearingsfor the tubes against the plate.

Each tube 3 isformedof a single piece of sheet metal having a Idownwardly extending lug 10 formed; onthe central forward portionthereof and two parallel lugs 11 eX- tending rearwardlyfrom the rearwardportion ofthe tube in spaced relation to each other and in spacedrelation to the top and the bottom of the tube. The rear plate 9 of theframe structure has a forwardly pressed, horizontally extendingindentation 12 therein; and the lugs 11 of each'tube extend therefrom tothe indentation 12 in the rear wall 9. The rearward ends of the lugs 1.1have shoulders 13 formed thereon which engage the indentationof the rearwall 9, and the lugs 11,. have lips or projections 14 which extendrearwardly from the shoulders 13 through openings in the wall 9 and therearward surface of the wall 9 within the indentation 12 therein toconnect the lugs 11 to the wall9. V

The downwardly extending lug 10 of each tube 3 is provided withshoulders 15 spaced below the bottom of the tube a distance equal to orslightly in excess ofthe thickness of the coins adapted to be carried bythe tube, and the shoulders 15 engage the top of the base late 8tc-retain the bet-tom f the tube in the proper spaced relation tothe topof the plate 8. Each lug is provided with-a lip or projection 16 whichextends downwardly member to stiffen the tubes and the tubes to stiffenthe frame member. The base plate 8 is providedwith coin dischargingopenings 17, one for each tube 3, which correspond in size with theinteriors of their respective tubes, and whichhave their centers locatedrearwardly of-the centers of their respective tubes. These openings 17are each provided'with a coin interruptingpart or shelf 18 which isformed integral with the base plate 8. Eachpart or shelf 18 extendsbelow the level of the body of theplate 18 and beneath the rearwardportion of its opening 17 in close proximity thereto; and each part orshelf 18 is constructed to be encountered by therearwardportion or sideof each coin discharged through its opening. 17, during its descenttherefrom, for a purpose hereinafter explained.

The base plate8 forms a support for stacks of coins within the tubes 8.The stacksof coins rest upon the base plate 8 and the lowermost coin ofeach stack is free to be moved rearwardly over the plate 8 and beneathits tube 3, and the coins above it to the discharge opening 17 back ofthe tube. When the bottom coin of a stack is thusmoved rearwardl thecoins above it are prevented from moving with it by the rearward wall ofthe tube 8 containing them. I shallnow describe the mechanism whichisoperable to move the coins from the tubes to the discharging openings17, one such mechanism being provided for each tube.

Slidable on the base plate 8 and beneath the tubes 3 are coinejectors.19 one for each tube, and each comprising a bottom part orplate I 20 havin a coinreceiviiw openin 21 therein *1 t: a b 7 a toppart 22spaced above and extending over the bottom plate 20 and arear'part 23 connecting the top and bottom parts 20, and 22,

allbeing formed .of a single piece of sheet metal, as clearly-shown inFig. 11.

Theseejectors 19are adapted to slide reare wardly and forwardly on thebase plate 8 and the sides of the bottom-plates 20 of the ejectors areguided by andbetween walls which project upwardlyfrom the'base plate 8and which are formedintegraltherewith. The

' walls which guidethe outer sides of the end ejector plates 20 ar'eformed by upturned anges 24 on the ends of the base plate 8, and

the walls which guide the inner sides of the endejector plates20andthesidesof the intubes 3 and projecting outwardly from the the sidesofthe ejector plates 20.

Each ejector plate 20 rests normally'in the forward position with itsopening 21 in registry withthe tube 3 above it to receive a cointierefroin, as shown full lines in Fig. 5, and when it is moved to thisposition its further forward movement is stopped by the top part 22of'the ejector engaging the back of its coin tube 3. v

l The forward end. portionofeach ejector plate 20 is cut out, at 27, topermit each plate 20 to clear the connecting lug 10 of its tube 3 whenthe plate 20 is moved rearwardly to the position shown by dot-and-dashlines in Fig. 5; and the width of theopening 27 of each plate is lessthan the diameter of the coinsto be ejected by the plate, so that, wheneach ejector. plate 20 is moved rearwardly from the position shown byfull lines to the posisides of the lower ends thereof directly abovetion shown by dot-anddash lines in Fig. 5,.

it will move the coin resting within its open- 21 from its tube 3 to anddischarge it through the discharging opening 17 back of its tube. v

The coin ejectors 19 are'adapted to be operated by levers 28, one foreach ejector. Each lever 28 is formed of asingle piece of sheet metal,as clearly shown in Fig. 10, comprising two spaced ejectoroperating armsor members 29 connected by apart 80, and a hand operated arm 81projecting forwardly from one of the ejector operating arms 29.

The upper end portions of the arms 29 of the levers 28 are fulcrumedonpins 32 which extend through the same and through the lugs 11 of thecoin tubes3, one lever 28 being fulcrumed on the-lugs 11 of each tube,and the lower end portions of the arms 29. of each lever 28 extend intoopenings 33. in the top part 22 of the underlying coin ejector 19. Thehandoperated arm 31 of each lever 28 extends around one side of its cointube 3 with its forward free end portion terminating in a convenientposition to receive the thumb of the person using the device when it isin service. 7

Each coin ejector 19 is'pressed normally forward with its top' part 22engaging the back of its coin tube 3, by a bifurcated spring 34 formedof a single piece of flat, resilient metal and constructed as clearlyshown in Fig. 12, and comprising a horizontal top plate or part 35 andtwo spaced, parallel arms 36 extending downwardly therefrom. Theconnecting member or-plate'35 of each spring 84 engages the lowersurface of the upper frame plate 7 and it is'secured thereto by meansofa securingpart or strip of metal over the same as shown in Fig. 5.

.37 Eigs.{ 1{and 5.) .whichextends around the bottom of the plate 35 andembracesthe same and has its end portions extended'up through openingsin. the top frame I plate .7 and bent The top plate 35 of each spring34Lis provided with a projection 38 which extends up through the topframe plate -.7 and is-bent overthe same with; one end portion ofitsconnecting part on stripfiil The lower end portions of the spring.arms-:36bear against the backs, of the lower .end portions'of the sidearms ormemv bersj 29 of the 'operating levers 28'to restore them-andtheir coin ejectors 19 to the normal position shown by full lines inFig. 5, after theyhave beenmoved therefrom and; released by thedepression and release of the hand op eratedarms 31 of the levers 28.

. Itwill now be understood that ifcoins be placed within each-tube 3 thestacks ofcoins will resttherein-supported by the base plate Swith thelowermost coins of the stacks within the openings- 21 of thecoinejectors, and

thateach timea hand operatedarm 31 is depressed thelowermost coin withinthe tube 3 governed by the armwill be ejected from the device. by beingmoved} rearwardly beneath the tube. to and discharged by gravity 1through the opening 17 ingthehb aseplate 8 rearwardly of the tube 3..

During the-operation of the change maker, the personusing thesame placeshis right hand infront of the device with the fingers thereof extendingbeneath the discharge opening 17 of thetube 3'from which he desires acom or coins, and he depresses the lever arm 31 for that tube with thethumb of the same hand, and each time he depresses the lever arm 31 acoin isidisch'argedfrom the opening 17 and intohis hand; As each coinfalls. from the discharge opening 17; the rearWa-rdfpon tion or side ofthe'coin encounters the coin interrupting part or shelf 18. beneaththerear ward part of theopenin'g 17,"therebycausing the forward portionofjeach coinlto descend in advance of the rearwardportionthereof.

Each coin interrupting part or shelf 18 is so constructed and related toits coin dischar in o enin' l7 that it not. 0111 causes the forwardportions of the coins falling from the opening to descend in advanceofthe rearwardportions. thereof but also to invert the coins and causethem to .fall substan tially' through a vertical path down into the handof the user of the device and tostack the coins oneupon another in thehand of the user. In Fig; 5, I haveshown by dot anddash lines severalpositions assumed by a coin during its descent from a. discharge opening17 to the hand of a user ofthedevice.

I have discovered that. this method of ejecting coins 'fro'm'a changemaker not only lessens the liability of accidentally; dropping coinsvfrom the hand of v the user but also increases, the speed. offmakingchange and lessens the'time heretoforerequired to ac.-

quire proficiency in using-achange maker. The rear. plate 9 of the framemember 215 Whichare located the vertical members or parts 41 of hooks 42as a means of pivotally" connecting the hooks t'o theendsof the framestructure ofthe. change maker; The hooks 42 are providedas a suitablemeans of attaching the device to the belt or other part of the wearingapparel of the user thereof.

Theloc'ationof the ears or projections .14 of the connectinglugs 11ofthe tubes 3, within thedepression 12 in, the rear plate 9 of the framestructure protects theclothinglof the user of the device from theotherwise wearing effect of the ears-or projections 0nthe clothing; I 7

I Each tube 3 is provided with a suitable re movable cap or cover L3havinga top providedwith a slot 44 through-which coins may be insertedinto the tube, and provided; also with a sleeve 45 surrounding .the tube3 and provided with an opening e6 therein to receive a projection 47formed onthetube to prevent accidentaldisplacement of the cap from thetube. When it is desired to remove the cap from the-tube, the tube orcapor. both .may be sprung from normal condition to free portion of whichis located between an arm- 29 of the leveranol the adjacent lug 11 ofthe coin tube and theother end portion-of which is bent around to engage.a head on one end of the pin- 82. By. bending the 1'? part 49from,engagement-with the head 50 the pin 32 may thereafter be withdrawnfrom i the lever arms 29 and the lugs 11 for the re moval ofthe lever.The lever arms 29 of each lever 28, embrace the two tube lugs 11 onwhich the lever is fulcrumed, thereby: pre venting lateral displacementof. the levers.
